VEGETABLE-CUTTER.

Application filed April 26, 1921.

To all whom it may concern Be it known that we, HARRY A. STODDA'RD andFRANCIS E. CALLAHAN, citizens of the United States of America, residingat C0- lumbus, in thecounty of Franklin and State of ()hio, haveinvented certain new and useful Improvements in Vegetable-Cutters, ofwhich the following is aspecification.

Our present invention relates generally to vegetable cutters and moreparticularly to slicing machines, our object being the provision of asimple inexpensive arrangement involving but few parts and capable of being maintained in a highly sanitary condition at all times, by whichvegetables, fruits and the like particularly potatoes and apples may besliced evenly and uniformly down to the last bit, without danger to theoperator and in fact mechanically without the presence of an operator.

With these objects in mind our invention proposes a slicing machine ofthe type and construction shown in the accompanying drawing, which formsa part of this specifieation, and wherein,

Figure 1 is a front proved machine,

Fig. 2 is a side View,

Fig. 3 is a front view with the cutter removed,

Fig. f is an enlarged vertical section taken centrally through the lowerportion of the machine, V

Fig. 5 is a horizontal section taken on an enlarged scale andsubstantially on line 5-5 of Fig. 3, and

I Fig. 6 is a top plan view partly broken away and in section of thecutter wheel.

Referring now to these figures our invention proposes a machine whichincludes a hopper 10 adapted to contain vegetables, fruit and the liketo be sliced, and open at its top for the reception of such articlesalthough it will be understood from the matelevation of our imter tofollow that the feed of articles to the from the hopper 10 and theopposite end of which leads to the front of the machine and communicateswith one end 12 of a Specification of Letters Patent.

spirally curved discharge slot 13 in a circular faceplate 1 1 with whichthe hopper is provided at its lower front portion.

The hopper 10 may be supported in any suitable manner as by means oflegs 15 and its face plate 14 presents a generally flat circular. faceat the front of the machine against which a cutter Wheel 16 rotates.This wheel is mounted upon an axial bolt 17 extending from the center ofthe face plate 1 1 and is preferably provided with a rim 18 which mayhave a circumferentially grooved portion 19 in casethe cutter wheel isto be driven by a belt. also provided for hand rotation of the cutterwheel and for cutting purposes this wheel A crank 20 is has its webradially separated and formed with inclined cutting blade'sQl as seen inI Fig. 6 which are laterally deflected toward the face plate 14: anduniformly inclined in the direction of rotation of thecutter wheel asindicated by the arrow in Fig. 1 so that it thus becomes apparent theentire series 1 of blades 21 maybe resharpened from time I p graduallytapers'and isof decreasing depth from the communicating end of thehopper feed channel, thus decreasing gradually in depth in the directionof rotation of the out ter wheel as shown so that as the articles aresliced they are automatically shifted by the action of the cutter wheelalong the 1 gradually decreasing slot and thus automatically fed intothe effective plane of rotation of the blades 21 down to the last bit ofvegetable of fruit as will be seen bya comparison of the dotted linepositions in Figure 5.

The wall of the feed slot 13 is moreover provided with teeth 22 inclinedas particularly seen in Fig. 5 in the direction of rotation of thecutter wheel 16 and consequently in the direction of shifting movementof the articles being sliced so that by virtue of these teethundesirable rotative or shifting movements of the articles which mightre sult in inaccurate and ununiform slicing is avoided. V

By curving the feed slot 13 of the face plate 14. as above described thearticles being sliced will more naturally and more readily follow rotarymovement of the cutter Wheel 16 and by arranging the lower dischargechannel of the hopperpn a spiral with one end communicating with the discharge slot it is quite obvious the articles 7 will readily and freelyfind their way into the slot of the face plate so as to avoid lying uponthe weight of articles within the hopper to cause a proper feed thereoffrom the hopper. This permits of effective slicing of the last-articlewithin the hopper as well as the first.

It is obvious from the foregoing that our invention provides a machinewhich may be readily operated, which may be formed of cutter, and ahopper having a feed channel and also having a, vertical faceplate atone side against which the cutter rotates, said face plate provided witha feed slot at its lower portion below the axis of the cuttercommunicating at one end with the said channel and gradually decreasingin depth therefrom in the direction of rotation of the cutter.

2. A' vegetable slicer including a rotary cuttergand a hopper havingafeed channel andzalso having a face plate against which the'cutterrotates, said faceplate provided with a feed slot communicating. atone'end with the said channel and gradually decreasing in depththerefromin the direction of rotation of the cutter, the wall of which slothaving teeth vinclined in the direction of -m'ove1nentofthe cutter asdescribed.

3. A vegetable slicer including a rotary cutter having a fiangedrim andhaving its wall within the rim radially separated and laterallydisplaced to form cutting blades, a hopper having a generally flat faceplate against which the rim and blades of the cutter wheel are movable,said hopper having a lower discharge channel and said face plate havinga feed slot communicating at one end with the discharge channel of thehopper and gradually decreasing in depth away from the said channel andin the direction of rotation of the cutter wheel. i

4. A vegetable slicer including a hopper having a circular face plate atone side of its lower portion and also provided'with a spiral dischargechannel in its base, said face plate having a curved feed slot in itsface communicating at one end with the discharge channel of the hopperand gradually decreasing in depth from the said channel, and a cutterwheel mounted to rotate against the face plate, having cutting bladesinclined toward the latter in a direction correspond ing'to the taper ofthe said feed slot as described. i i 5. A vegetable slicer including ahopper having a circular face plate at one side of its lower portion andalso provided with a spiral discharge channel in its base,'said faceplate having a curved feed slot in its face communicating at one endwith the discharge channel of the hopper and gradually decreasing indepth from the said channel, and a cutter wheel mounted to rotateagainst the face plate, having cutting blades inclined toward the latterin a direction correspondin to the taper of the said feed slot, saidfeed slot having its wall provided with teeth inclined in the directionof its taper as and for the purposes set forth.

In testimony whereof we have affixed our signatures. Y a
